DETAILED DESCRIPTION

According to the embodiments of the present subject matter, there is provided a method and apparatus for providing context-aware input data to an application running on a computer system. Detailed description is presented below for each embodiment of the present subject matter with reference to the figures.

There are usually many restrictions on input values for input fields of various applications. For example, the input value for an input field of telephone numbers for a certain area in Beijing is restricted to an eight-digit integer starting with “+86-10.” For different input fields of a same application or different applications, their input values may possibly have an association relationship between them. For example, information such as “product number” and “manufacturer” needs to be input into an order system, subsequent to which the same information needs to be input into another financial system. This requires a manual copy/paste operation. Another circumstance is also possible in which an application includes two input fields “product unit price” and “amount,” and another application may include only one field “product total price”; such that the input values satisfy the expression “product total price”=“product unit price” multiplied by (e.g., ×) the “amount.” At this point, manual calculation and input may also be needed.

Daily inputting repeated data into various applications is a dull and time-consuming task. Any inputting error may lead to an invalid order, or other errors may cause a huge loss. Furthermore, people have to spend considerable time on the inefficient manual copy/paste procedure, which is not only inefficient but also error-prone.

Although there already exist a plurality of inputting methods having a memorizing function, these inputting methods merely provide prompts regarding input content candidates for a user's input by memorizing a vocabulary frequently used by the user recently or by manually configuring short cut keys to several commonly used words. However, such prompts merely provide the user with very limited input assistance.

For a specific user who needs to enter inputs into input fields of various applications every day, when the user repeatedly inputs information into applications for a long time, for purposes of the present subject matter it may be assumed that the user's inputting behavior is predictable (i.e., data input by the user has similarity during a specific period of time). It may also be assumed that data to be input into the application by the user has similarity, or inputs may be selected from an “input data pool,” instead of entirely relying on manual inputting or “Ctrl+C/Ctrl+V” copy/paste operation of an operating system.

A method according to some embodiments of the present subject matter comprises: generating in advance external constraints for at least one input field of at least one application; based on the external constraints, providing context-aware input data to at least one input field of a currently used application. The external constraints mentioned herein refer to external constraints generated in advance on input data for a single input field and external constraints generated in advance based upon the association relationship between input data for two or more input fields. The external constraints generated in advance may be stored in an application locally or in a database of a dedicated or general-purpose server for sharing by other users.

FIG. 1 schematically illustrates a schematic view 100 of an example of an implementation of an application environment in which a method according to an embodiment of the present subject matter may be implemented. As illustrated in FIG. 1, the user may utilize the method according to the present subject matter at different types of user terminals, such as a desktop computer 110-1, a laptop computer 110-2, a panel computer 110-3, a personal digital assistant (PDA) 110-4, and a mobile terminal 110-N.

It should be noted that according to embodiments of the present subject matter, external constraints as generated in advance may be locally stored in a user terminal running various applications, and further, they may be stored in a dedicated server 120, so that users may access the external constraints from respective user terminals 110-1 to 110-N via a network 130. Further, it should be noted that according to the embodiments of the present subject matter, the external constraints may be located in at least one dedicated or general-purpose server that is external to the respective user terminal, in a concentrated or distributed manner.

Hereinafter, with reference to FIG. 2, detailed description is presented for the operation of providing input data according to the embodiments of the present subject matter. FIGS. 2A-2D schematically illustrate example implementations of various input fields in an example application. According to an embodiment of the present subject matter, the input field may be a text input box 202 in an application as illustrated in FIG. 2A, wherein the input field is not limited to the text input box 202 for inputting data but may include, without limitation, a radio button (as illustrated by 204 in FIG. 2B), a check box, a drop-down menu (as illustrated by 206 in FIG. 2B), a selection menu, a text input field, various data fields for inputting data, respective pages in an application (as illustrated by a tab 208 in FIG. 2C), and an individual electronic data sheet 210 (e.g., an Excel® spreadsheet) as illustrated in FIG. 2D, or any other sheet in electronic tabulation tools.

It should be noted that the method according to the present subject matter may apply to applications of different language interfaces. For example, the input field “

” in Chinese and the input field “country” in English actually represent the same meaning in different applications, so external constraints between them may be pre-defined. That is, the method according to the present subject matter is not limited to languages used in respective applications or the type of a language input by the user. Rather, the method according to the present subject matter is applicable to any languages, so long as the user has pre-defined external constraints on one or more input fields of one or more applications.

FIG. 3 schematically illustrates an operation procedure 300 of an example of an implementation of a device according to an embodiment of the present subject matter. Blocks 310-1 to 310-M illustrate multiple applications. The device according to the present subject matter may provide data with respect to input fields of the multiple applications. As illustrated in the right side of FIG. 3, the device according to the present subject matter may include two portions, namely a provision component 320 and a generation component 330. The generation component 330 includes a first generation component 332 for generating a first external constraint and a second generation component 334 for generating a second external constraint. A configuration data repository 336 and an input data repository 338 may be located within the generation component 330 or in a remote server.

According to an embodiment of the present subject matter, the first generation component 332 and the second generation component 334 obtain inputs with respect to applications 310-1 to 310-M (as illustrated by arrow A) in the procedure of generating external constraints in advance. There are many options for obtaining inputs: 1) user inputs may be obtained by monitoring keyboard events, (e.g., every time the user presses a keyboard key, information on the pressed key may be obtained simultaneously or instantly) and information on respective pressed keys may be combined to form an input with respect to a current input field; 2) after the user has entered all content of the current input field, overall input information may be obtained from the current input field. An advantage in adopting the second option is that information obtained every time the user presses a key does not need to be saved or processed, and all input data may be collected at a time after the user completes the input. In this manner, it may be possible to obtain information that the user wants to input into the input field ultimately, without inputting scattered characters. This may be conspicuous in a situation that the user utilizes a Chinese input method, for example. When the user wants to input “

,” the input value “

” may be obtained by simply inputting “zhongg” and pressing the Spacebar in some input methods that support Pinyin (a Chinese language transcription system) for initial letters, at which point the keyboard event being monitored may be an event of consecutive letters “zhongg” and pressing the Spacebar.

According to the embodiments of the present subject matter, generating external constraints in advance further includes determining the identification of the application, and determining the identification of the input field. For example, an application ID and an input field ID may be obtained as the identifications by using Windows® application programming interface (API) or other means. In the subsequent processing procedure, the application ID and the input field ID may be jointly used as an identifier for differentiating the input field. According to the embodiments of the present subject matter, the identification of a page in the application may further be obtained.

The first generation component 332, as illustrated in FIG. 3, may be used for generating in advance a first external constraint with respect to input data to a single input field. The first external constraint refers to the restrictions on content of the input field in the application. For example, the input value for the input field “product model” may be restricted to a specific model existing in a product list; the input value for the input field “zip code” may be restricted to a multi-digit integer of a numeric type; the input value for the input field “country” may be restricted to the name of a specific country.

The second generation component 334 may be used for generating in advance a second external constraint with respect to the association between input data of two or more input fields. The second external constraint refers to the restrictions on the relationship between different input fields (in a same or different applications). For example, the same application may include input fields such as “City,” “Country,” “Area Code,” and “Zip Code.” It is to be understood that these input fields may have an association. Once the input value for the field “City” is determined, content of the input fields “Country,” “Area Code,” and “Zip Code” may be determined. A second external constraint between these input fields may be defined. For another example, an application in a Chinese interface may have input fields such as “

,” “

,” “

,” and “

” in Chinese and another application may have the input fields “City,” “Country,” “Area Code,” and “Zip Code” in English, so a second external constraint may be defined with respect to corresponding fields of these two applications. For example, the second external constraint may be defined in the form of Table 1 below. It is to be understood that Table 1 is illustrative and the external constraints may be defined in any feasible form according to embodiments of the present subject matter.

TABLE 1 Second External Constraint

City

Country

Area Code

Zip Code

It should be noted that for a specific input field, there may exist no or more first/second external constraints. For example, the input field “

” (zip) may have the following constraints: a first external constraint defining input data as a multi-digit integer, a second external constraint associating “

” (zip) with “

” (city), “

” (country), and “

” (telephone number), and a third external constraint associating “

” (zip) with the input field “Zip Code” in another application.

According to the embodiments of the present subject matter, the configuration data repository 336 may be used for storing external constraints that have been generated in advance, and the input data repository 338 may be used for storing user-input historical records or a pre-defined data repository, such as a list of legitimate vendors (e.g., data input by the user with respect to the input field in the application). The generation procedure may be as illustrated by arrow B in FIG. 3, in which the first generation component 332 and the second generation component 334 save the generated external constraints and the obtained historical input data to the configuration data repository 336 and the input data repository 338, respectively.

It should be noted that the external constraints mentioned here are generated in advance. As such, an initialization procedure does not have to be performed every time input data is provided using the method according to the present subject matter. The external constraints generated in advance may be saved in a remote server for sharing by multiple users. Different external constraints may be generated with respect to different user classes of users. Further, the user may save private external constraints, which are customized according to his/her personal information, locally at the client terminal, while accessing common external constraints from the remote server.

According to the embodiments of the present subject matter, after the external constraints are generated, the configuration of the external constraints may be modified dynamically with respect to a current application during usage, such as adding a new external constraint, deleting an obsolete external constraint, or updating an existing external constraint. In addition, the external constraints do not remain unchanged; rather, they may be adjusted continuously throughout the procedure of using the method according to the present subject matter. That is, the procedure of generating external constraints may be a cyclic update procedure that undergoes times of modification.

Hereinafter, referring to FIG. 3, description is presented for the procedure of providing context-aware input data to at least one input field of a current application based on external constraints. As illustrated in FIG. 3, the provision component 320 is coupled to the applications 310-1 to 310-M for obtaining application IDs, input field IDs, and current user input values from the applications. After querying the configuration database 336 and the input database 338 as illustrated by arrow C, the provision component 320 provides context-aware input data to corresponding input fields of the applications 310-1 to 310-M in the direction as illustrated by arrow D.

Hereinafter, referring to FIGS. 4A-4D, detailed description is presented for an example of an implementation of an operation interface 400 regarding how to provide context-aware input data to an input field of an application according to different embodiments of the present subject matter. The operational interface 400 may include one or more user interfaces, as shown within the examples of FIGS. 4A-4D, for receiving and outputting data. Providing context-aware input data includes determining the identification of the application and the identification of a current input field, and detecting/obtaining a current input value, such as via the user interface; and based on the above data, implementing as input data the context-aware data associated with the current input value as defined in the external constraints. In the procedure of providing input data, the identification of the application, the identification of the input field, and the current input value as detected/obtained may be used as keywords for retrieving corresponding external constraints.

Additionally, in the case that the application includes multiple pages (e.g., including multiple tabs as illustrated in FIG. 2C), the page identification of the application should be identified, and input data may be provided based on the identification of the application, the page identification, the identification of the input field, and the current input value. For different applications, it may be useful to determine other identifiers other than the identification of the application and the identification of the input field, aiming at uniquely locating the current input field.

FIG. 4A schematically illustrates a schematic view of providing a prompt to a user regarding input data candidates according to an embodiment of the present subject matter. A prompt with respect to a specific input field may be pre-configured among the external constraints, for example, by expressing a character string or a character string that may be difficult to remember by using a phrase that is easy to remember, or expressing a relatively long input by using abbreviation characters.

In an order system, for example, the input value for the field “Vendor ID” may be restricted to the number of a specific vendor, whereas these numbers may be difficult to remember. As such, it may be predefined in the external constraints that character strings “CompanyA” and “CompanyB” represent the vendor numbers “9878987” and “1273645,” respectively. As illustrated in FIG. 4A, when it is detected that “Company” is input to the input field “Vendor ID,” vendor numbers corresponding to the user input may be provided as candidates in a prompt box 402 for selection by the user.

In an embodiment of the present subject matter, the user may utilize the prompted input data to modify or fill in the current input field, for example, by using numeric keys or up and down keys for selection.

In an embodiment of the present subject matter, the prompted/modified input data may be utilized to modify or automatically fill in the current input field with the prompted/modified input data and at least one other input field that has an external constraint relationship with the current input field with context-aware input data. Specifically, FIG. 4B schematically illustrates a schematic view of automatically filling input data in the current input field according to an embodiment of the present subject matter. As described above, external constraints have been established in advance with respect to the fields “City,” “Country,” “Telephone,” and “Zip Code” in the application. That is, these input fields have association relationships. When the user inputs an input value to any of the fields, inputs to other fields may be located from the external constraints, and other input fields are filled in automatically.

For example, the user inputs “Beijing” to the field “City” as illustrated in FIG. 4B. As known from the external constraints, “Beijing” is a Chinese city, its telephone area code is “+86-010,” and its Zip Code is “100000.” Hence, these input values may be automatically input to corresponding input fields (an interface after the automatic inputting is as illustrated in FIG. 4B). It should be noted that after the user enters an input to any input field, input values for other input fields that are associated with this input field may be “associated,” regardless of the order of input fields in the interface. For example, when the user inputs “100000” to “Zip Code,” it is known, again according to the external constraints, that “100000” is the zip code of “Beijing,” “Beijing” is a Chinese city and its telephone area code is “+86-010.” So these values are automatically filled in corresponding input fields.

According to the embodiments of the present subject matter, it is possible to modify the filled input value or provide a prompt regarding possible errors in the current input data, through “association.”

According to an embodiment of the present subject matter, the validity of the current user input value may be verified. For some input fields whose content is strictly restricted, it may be prudent to ensure the correctness of an input value, as such the present subject matter provides a tool for verifying whether an input is valid. Verifying the validity of an input may be divided into mandatory verification and suggestive verification or other verification manner. Mandatory verification may be used for input fields having relatively tight constraints, such as product number, vendor number, and so on. When a user input value is invalid, a prompt may be provided to the user, informing that the input value is invalid (as illustrated by the prompt box 404 in FIG. 4C), and the prompt may be maintained until the user inputs a valid value. Suggestive verification may be used for input fields having relatively loose constraints. When it is detected that there may be an invalid user input, an alert may be provided to the user, prompting the user to check whether the current input value is correct.

According to an embodiment of the present subject matter, it is possible to process the input value for at least one input field in a first application, process/output information associated with the input value to at least one corresponding input field in a second application. FIG. 4D schematically illustrates a schematic view of processing/outputting content of respective input fields between different applications according to an embodiment of the present subject matter.

Application user interfaces 410 and 420 illustrate respective interfaces of the first application and the second application. External constraints have been predefined with respect to input fields in these two applications with input fields with the same name in the two applications that have the same input data. Hence, all input values having external constraints and filled in the first application by the user may be completely processed/output into corresponding input fields in the second application. However, it is to be understood that names of input fields of multiple applications do not necessarily need to be identical to each other (which may be, e.g., “telephone” and “telephone number,” respectively) so long as external constraints have been predefined.

An application user interface 430 illustrates an interface resulting from processing/outputting input data from the first application user interface 410 into the application user interface 420. The user may process/output input data between input fields that have external constraints, by a shortcut key, a functional button, or other manners. For example, FIG. 4D illustrates input values for input fields “telephone” 412, 422, prior to the processing/outputting, and input field 432 subsequent to the processing/outputting.

The “process/output” operation in the foregoing example may be construed as a “super copy/paste” operation to some extent, that accomplishes more functions than conventional “copy/paste” operations. The “process/output” operation according to the foregoing embodiment of the present subject matter is not limited to, for example, the “Ctrl+C/Ctrl+V” function in the Windows® operating system, but may comprise complex operations implemented according to the predefined external constraints. According to the embodiments of the present subject matter, it is possible to process input data in an application and process/output the processed data to associated input fields. Other examples of the “process/output” operation are presented below:

Example 1

A first application includes the input fields “unit price” and “amount,” and a second application only includes the input field “total price.” At this point, external constraints may be established between input fields of these applications, such that an input value meets the following Equation (1):

total price=unit price×amount  Equation (1):

If the user inputs “100” to “unit price” and “10” to “amount” in the first application, when the user requests the “process/output” operation, “1000” may be filled in the input field “total price” in the second application.

Example 2

A first application includes two input fields, namely “area code” and “telephone number,” and a second application only includes the input field “telephone.” At this point, external constraints may be established between input fields of these two applications, such that input data of the field “telephone” in the second application is a character string connection of input data of the two fields “area code” and “telephone number” in the first application and uses a dash “-” as a separator.

If the user inputs “+86-010” to “area code” and “12345678” to the field “telephone number” in the first application, when the user requests the “process/output” operation, input data “+86-010-12345678” may be filled in the input field “telephone” in the second application.

Example 3

A first application may utilize English interface display and includes the input field “City,” and a second application may utilize Chinese interface display and includes the input field “

.” External constraints may be established between input fields of the two applications, such that when the user inputs an English city name to the field “City,” the Chinese name of the input city is automatically filled in the field “

” in the second application.

For example, when the user inputs “Beijing” to the field “City,” “

” (Beijing) is automatically filled in the field “

” (City).

It should be noted that the above examples illustrate non-limiting examples of the “process/output” operation that may be implemented according to the present subject matter. It is possible to use an input field of a first application as an input for certain operations and output results to corresponding input fields in a second application based on other external constraints. The operations include, without limitation, a mathematical operation, a logical operation, a character operation, and other types of feasible operations. According to the embodiments of the present subject matter, external constraints may be established between input fields of multiple applications, so that an input value for an input field in at least one application may be used as an input and context-aware input data may be provided to an input field of at least one other application.

FIG. 5 schematically illustrates a flowchart 500 of an example of an implementation of a method for providing context-aware input data. As illustrated in FIG. 5, external constraints are generated in advance with respect to at least one input field of at least one application in step S502. It should be noted that the step of generating external constraints may be a preprocessing step which may be performed by an administrator or other person, independent of the current user. The generated external constraints may be stored in a storage location that is accessible to user devices.

In step S504, context-aware input data is provided to at least one input field in a currently used application based on the external constraints. According to the embodiments of the present subject matter, context-aware input data may be provided in various manners, including providing input data candidates, modifying or automatically filling in a current input field, verifying validity of a current input value, and the “process/output” processing that have been described above with reference to FIGS. 4A-4D.

FIG. 6 schematically illustrates a detailed flowchart 600 of an example of an implementation of an embodiment of step S502 for generating external constraints as illustrated in FIG. 5. The external constraints may be a first external constraint with respect to an input field per se and a second external constraint with respect to the association between input fields, respectively. The first external constraint relates to the restrictions on field content per se, and various implementations of the first external constraint may be achieved based upon the present subject matter. Hence, the procedure of generating external constraints in advance is explained below in the context of establishing the second external constraint.

In step S602, the identification of at least one application is determined. In step S604, identifications of at least two input fields of the at least one application are determined. In step S606, restrictions on input values for the at least two input fields of the at least one application are identified. In step S608, an association relationship is established between the identification of the at least one application, identifications of the at least two input fields of the at least one application, and the restrictions on input values for the at least two input fields of the at least one application. It should be noted that an additional operation of obtaining a page identification may be used in an embodiment of the present subject matter.

Hereinafter, detailed description is presented for the operation procedure of providing input data according to the embodiments of the present subject matter in the context of complex “process/output” processing.

Reference is made back to FIG. 4D when explaining the “process/output” operation. As illustrated in FIG. 4D, for example, the input field “Telephone” 412 of the first application interface 410 and the input field “Telephone” 422 of the second application interface 420 are identified, and external constraints of “process/output” are established between the two input fields, which is as illustrated in the following tables.

TABLE 2 Content of Application 1 Content of Application Application ID APP-001 Page ID Page-001 Field name Telephone

TABLE 3 Content of Application 2 Content of Application Application ID APP-002 Page ID Page-002 Field name Telephone

TABLE 4 Process/Output Rule Process/Output Rule Rule ID Rule-001 Source application ID APP-001 Source page ID Page-001 Source field Telephone Target application ID APP-002 Target page ID Page-002 Target field Telephone

The above Table 2 through Table 4 illustrate external constraints for processing/outputting the input field 412 of the first application interface 410 to the input field 422 of the second application interface 420. In addition, external constraints may be defined likewise for other input fields in the first and the second applications, so that all input fields in the first application may be “processed/output” to corresponding fields in the second application by using the external constraints.

Hereinafter, referring to FIGS. 7A and 7B, description is presented for the flow of the “process/output” operation in an embodiment. After “process/output” external constraints are defined, input content may be processed/output from the first application to the second application. FIG. 7A schematically illustrates a detailed flowchart 700 of an example of an implementation of an embodiment of the “process” (understood as “super copy” to some extent) operation for input processing and identification/creation of context-aware input data. The flow starts with a hot key processing illustrated in step S702 a, for initiating the “process/output” processing according to the present subject matter. It should be noted that the hot key processing mentioned here may be the processing of a shortcut key as defined according to the embodiments of the present subject matter (for example, it may be defined as “Ctrl+Shift+C” or other shortcut key so as to be distinguished from the shortcut key “Ctrl+C” of the operating system) or the processing of another button or menu for activating the “process” function.

Next, an application identification and a page identification are obtained in step S704 a, which are respectively App-001 and Page-001 in this example. In step S706 a, it is determined whether or not there are external constraints for the process/output of a current page. If not, the operation flow ends; if yes, the flow proceeds to step S708 a in which the process/output data associated with the current page is loaded based on the external constraints.

When the flowchart illustrated in FIG. 7A ends, the user has loaded input data for various input fields for outputting to other applications. FIG. 7B schematically illustrates a detailed flowchart 701 of an example of an implementation of an embodiment of the “output” operation for context-aware input data. Like the output of the hot key in step S702 a, the hot key output function is initiated in step S702 b. Subsequently in step S704 b, an application identification and a page identification are obtained, which are the application ID App-002 of the second application (currently in an active state) and the page identification Page-002. It is then determined in step S706 b whether or not there are external constraints for the process/output of a target page. If not, the flow then ends; if yes, the flow proceeds to step S708 b.

As described above, because external constraints are already present in the current process/output processing (as illustrated in Table 4), data is obtained from data sources (i.e., the source application App-001, the source page Page-001, the source field Telephone) as indicated by the external constraints in step S708 b. In step S710 b, the obtained data is provided to corresponding input fields of a target application, namely, the target application App-002, the target page Page-002, and the target field Telephone. At this point, the input value for the field Telephone in the second application is the same as that for the field Telephone in the first application, which is “1234567890” (see FIG. 4D).

For the process/output operation of other input fields in the application, the operation flow is similar to that as described above, and as such, details thereof are omitted. According to an embodiment of the present subject matter, it is possible to optimize the procedure of processing/outputting multiple input fields in the application, e.g., by dividing input fields to be processed/output into groups and defining the process/output operations for the groups.

It should be noted that the process/output operation according to the embodiments of the present subject matter is more sophisticated than conventional copy, due to a mapping relationship between respective input fields of an application or between input fields of another application on the basis of predefined external constraints. Although examples are presented for processing/outputting input data in one-to-one correspondence between input fields of two applications, it should be understood that the process/output processing according to the present subject matter may include, without limitation, a mathematical operation, a logical operation, a character operation, and other types of feasible operation.

It should be understood that the “hot key process” and “hot key output” operations in FIGS. 7A and 7B are two sequential operations having a cause-and-effect relationship. Once the user triggers the hot key process function in the first application, input data of an input field in the first application, for which external constraints are defined, is loaded. When the user switches to the second application, the loaded input data may be provided to a corresponding input field of the second application by triggering the hot key.

It should be understood that according to an embodiment of the present subject matter, data may be processed/output between the first application and the second application by setting a “bidirectional” mark, such that the process/output is implemented in a two-way manner.

The foregoing “process/output” operation as illustrated in FIGS. 7A and 7B may be understood as “super copy” and “super paste.” According to the embodiments of the present subject matter, the “super copy” and “super paste” operations may be implemented with respect to input values for multiple input fields of at least one application. Those skilled in the art may perform the operations with reference to the steps illustrated in FIGS. 7A and 7B based upon the description herein.

For example, the page of the first application includes the input fields “unit price” and “amount,” and the user inputs “100” to “unit price” and “10” to “amount” in the first application. In addition, the user desires input data “1000” to be automatically filled in the input field “total price” in the second application. Like step S706 a in FIG. 7A, it is determined whether or not there are external constraints for “process/output” of the current page, and in this example the external constraint is “total price=unit price×amount.” Like step S708 a in FIG. 7A, mapping data (i.e., 100×10=1000) associated with “process/output” of the current page is loaded. Like the step S710 b illustrated in FIG. 7B, the input data “1000” is filled in the input field “total price” in the page of the second application.

According to the embodiments of the present subject matter, it is possible to utilize a standalone tool to provide a method for providing context-aware input data to an application running on a computer system, and the standalone tool may be used in a user's client terminal.
